Company Overview

Message from Presidents

We have established DG Capital Group to realize "Digital Grid" technology that operates and maintains power systems functionally with autonomous and interdependent devices distributed across a network, much like the Internet.
Our group's subsidiary companies develop hardware such as time-synchronized Grid Forming inverters (Digital Grid Routers: DGR), small and medium-sized lift-type vertical-axis wind turbines, and stationary brush DC motor generators to achieve a shift to renewable energy. We aim to simplify the operation of local distribution networks for municipalities, and assist in the process of enabling regional autonomy, funded by the revenues from electrical businesses.
Therefore, we are dedicated to the diligent pursuit of our company's growth and sincerely request your continued support and patronage.

DG Capital Group Co., Ltd
President & CEO
Rikiya Abe

In September 2011, the Digital Grid Consortium, a non-profit organization, was launched in Japan. It is represented by Dr. Rikiya Abe, the developer of the Digital Grid and former specially appointed professor at the University of Tokyo. In pursuit of an era where renewable energy becomes the main power source and realizing an energy society with zero marginal cost (a new power grid system), we have had the honor of establishing DG Capital Group in July 2020. DG Capital Group is a collective of companies that develop and manufacture devices to connect 100% renewable energy distribution networks to conventional systems. These companies include those developing and manufacturing digital generators and motors, batteries, wind turbines, those operating distribution networks, those expanding these technologies internationally, and retail electricity businesses. We are advancing regional revitalization projects based on a Rural Enterprise Model, where the electricity produced is sold on the Digital Grid Consortium's platform (DGP) through its members.
The Digital Grid is the "Internet of Energy". The Digital Grid Router (DGR) enables widespread adoption of renewable energy, while envisioning a world where energy consumption benefits all life on Earth, minimizing environmental damage. We aim to adopt this innovative digital grid solution on a global scale, contributing to the creation of a low-carbon society.
DG Capital Group aims to bring happiness to people through the power revolution.
Therefore, we are dedicated to the diligent pursuit of our company's growth and sincerely request your continued support and patronage.
